👉 The term "sigmoidal" refers to a mathematical function that is often used in machine learning and neural networks. In this context, it means that such functions are capable of producing output values between 0 and 1 (inclusive), which makes them useful for representing binary outputs or probabilities. The sigmoid function, also known as the logistic function, takes any input value and produces an output value based on a non-linear relationship with the input value. It is often used in neural networks to represent complex data
